Programme Director: Kari Rummukainen
The aim of the Theory Programme is to conduct research of high standard in a few selected subject fields for which HIP can act as a center of excellence in Northern Europe.
Theory Programme is divided into projects, the leaders of which have the responsibility of coordinating the activities in their field. There is a special emphasis on recruiting graduate students and supporting the career formation of young researchers. International collaboration is a high priority, as witnessed by the strong international ties of the Projects. Collaborative efforts between the Projects are encouraged.
Apart from the EU and Nordic networks, the main external funding source is the Academy of Finland, together with private foundations.
- High Energy Phenomenology in the LHC Era Personnel
The project has a broad scientific agenda addressing topical questions of high energy phenomenology ranging from collider physics to cosmology. The project members are based at the Department of Physics of the University of Helsinki, but active collaboration links exist to a number of universities and research centers both in Scandinavia and elsewhere.
- QCD and Strongly Interacting Gauge Theory Personnel
Quantum Chromodynamics (QCD) is firmly established as the correct theory of the strong interaction and a cornerstone in the Standard Model of particle physics. It describes the confinement of quarks and gluons into hadrons, and their deconfinement in hot and dense systems. In spite of the apparent simplicity of the Lagrangian that defines the theory, QCD presents a complicated challenge for attempts to calculate physical observables.
- Theoretical Cosmology Personnel
The goal of the project is to connect the observed properties of our universe to fundamental theories of matter and gravity. We study the origin and evolution of the universe using a complementary set of theoretical methods, opening new connections between particle physics and cosmology.
- Topological Matter Personnel
The notion of symmetry has traditionally served as a guiding principle in understanding ordered phases of matter. In the last two decades, topology has been recognized as complementary but equally fundamental concept.
